MaskFilter

class MaskFilter

MaskFilter is the base class for object that perform transformations on the mask before drawing it.

An example subclass is Blur.

Subclasses

`ShaderMaskFilter`
`TableMaskFilter`	Applies a table lookup on each of the alpha values in the mask.

Members:

Methods

`Deserialize`
`MakeBlur`	Create a blur maskfilter.
`__init__`
`getFlattenableType`
`getTypeName`	Returns the name of the object's class.
`ref`	Increment the reference count.
`serialize`
`unique`	May return true if the caller is the only owner.
`unref`	Decrement the reference count.

Methods

static MaskFilter.Deserialize(data: Buffer) → skia.MaskFilter

static MaskFilter.MakeBlur(style: skia.BlurStyle, sigma: float, respectCTM: bool = True) → skia.MaskFilter

Create a blur maskfilter.

Parameters:

style (skia.BlurStyle) – The BlurStyle to use
sigma (float) – Standard deviation of the Gaussian blur to apply. Must be > 0.
respectCTM (bool) – if true the blur’s sigma is modified by the CTM.

Returns:

The new blur maskfilter

MaskFilter.__init__(*args, **kwargs)

MaskFilter.getFlattenableType(self: skia.Flattanable) → skia.Flattanable.Type

MaskFilter.getTypeName(self: skia.Flattanable) → str

Returns the name of the object’s class.

Implemented in Drawable.

MaskFilter.ref(self: skia.RefCntBase) → None

Increment the reference count.

Must be balanced by a call to unref().

MaskFilter.serialize(self: skia.Flattanable) → skia.Data

MaskFilter.unique(self: skia.RefCntBase) → bool

May return true if the caller is the only owner.

Ensures that all previous owner’s actions are complete.

MaskFilter.unref(self: skia.RefCntBase) → None

Decrement the reference count.

If the reference count is 1 before the decrement, then delete the object. Note that if this is the case, then the object needs to have been allocated via new, and not on the stack.
